Description

Technical Field

[0001] The present invention relates to the technical field of tunnel fire fighting, and in particular to a structure of a portable intelligent fire fighting box for a tunnel and a use method thereof. Background Art

[0002] With the continuous development of modern transportation infrastructure, the importance of tunnels in the transportation network has become increasingly prominent. However, tunnels are relatively closed and narrow. Once a fire occurs, the fire spreads quickly, smoke is difficult to disperse, and rescue is extremely difficult, which often causes serious casualties and property losses.

[0003] Traditional tunnel fire extinguishers have gradually exposed many drawbacks when dealing with such complex and dangerous fire scenarios. In terms of fire extinguishing function, most of them are only equipped with a single type of fire extinguishing agent, and cannot effectively extinguish different types of fires (such as Class A solid fires, Class B liquid fires, Class C gas fires, etc.). For example, in the face of Class B fires caused by oil, ordinary dry powder fire extinguishers are difficult to achieve the best fire extinguishing effect, which can easily cause the fire to continue to spread.

[0004] In terms of smoke exhaust, the traditional fire extinguisher box and the tunnel ventilation system are independent of each other and lack an effective linkage mechanism. When a fire produces a large amount of smoke, it is difficult to quickly and accurately exhaust the smoke by relying solely on the tunnel's own ventilation system, resulting in extremely low visibility at the fire scene, which not only seriously affects the development of firefighting and rescue work, but also greatly increases the difficulty of evacuating trapped people.

[0005] In terms of power supply, traditional fire extinguisher boxes usually rely on external power supply. Once a fire causes a power supply system failure, the intelligent devices in the box (such as fire alarm devices, communication equipment, etc.) will not work properly, seriously affecting the function of the fire extinguisher box. Especially in tunnels in remote areas, the external power supply is unstable, which increases the risk of the fire extinguisher box not being able to operate normally at critical moments. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a structure of a portable intelligent fire fighting box for tunnels and a method of using the same.

[0014] Preferably, a solar panel is fixedly connected to the top of the fire fighting box, a lithium battery pack is arranged on the inner wall of the solar panel, and a charging management chip is arranged on one side of the lithium battery pack.

[0015] Preferably, the outer wall of the fire fighting box is provided with a hinge, and the fire fighting box is rotatably connected to a control mainboard via the hinge.

[0016] A method for using a portable intelligent fire fighting box for a tunnel comprises the following steps:

[0017] Step S1: assemble the bottom box panel, the front box panel, the rear box panel, the left box panel, the right box panel, and the top box panel in sequence along the folding joints to form a complete fire fighting box, and then assemble each module into the fire fighting box in sequence;

[0018] Step S2: placing the fire fighting box in the tunnel, and when a vehicle is driving or the ground vibrates due to a fire, the energy collection and management module is used to generate electrical energy to reserve energy for subsequent equipment operation;

[0019] Step S3: The temperature sensor tracks the temperature changes in the tunnel in real time, the gas sensor monitors the concentration of combustible gas, and the flame sensor captures the flame characteristics. Then the multi-sensor fusion module transmits the collected data to the central processor in real time;

[0020] Step S4: The central processor receives the data transmitted from the multi-sensor fusion module and determines the fire type and fire size according to the fire judgment algorithm. At the same time, the smoke concentration sensor monitors the smoke concentration in the tunnel. If the smoke concentration exceeds the predetermined threshold, the central processor sends a smoke exhaust request to the axial flow fan.

[0021] Step S5: Based on the fire judgment result, the central processor determines the type of fire extinguishing required, then controls the flow control valve of the corresponding storage tank and accurately adjusts the flow of the agent, and selects an appropriate spray mode according to the actual situation on site to control the fire. During the spraying process, the multi-sensor fusion module continuously monitors the fire situation, and the central processor adjusts the spray mode in real time based on the feedback data. Each storage tank is equipped with an independent pressure sensor and liquid level sensor to monitor the pressure and liquid level of the agent in real time;

[0022] Step S6: After receiving the smoke exhaust request, the central processing unit controls the operation of the smoke exhaust control module, and then drives the axial flow fan and the electric control valve to open. The axial flow fan absorbs the smoke in the fire scene through the connecting pipe, and the filter plate intercepts the large particles mixed in the fire scene. Then the smoke enters the smoke exhaust pipe through the U-shaped pipe, and the purified air is discharged after being filtered by the air purification filter. During this process, the smoke concentration sensor and the air quality sensor continuously monitor the smoke concentration and air quality. The central processing unit adjusts the opening of the electric control valve in real time according to the monitoring data until the smoke concentration is reduced to a safe range.

[0023] The beneficial effects of the present invention are:

[0024] The fire extinguisher box adopts a box design with folding joints and mortise and tenon structures, so that the fire extinguisher box can be greatly folded to reduce the volume when carried, making it more portable and convenient to transport to the tunnel site. After arriving, it can be quickly unfolded and assembled into a complete box through the cooperation of the tenon and the mortise, the clamping block and the clamping groove. It is easy to operate. Compared with the traditional fixed structure fire extinguisher box, it has more installation and deployment flexibility in the narrow space or complex terrain of the tunnel. The position and status can be quickly adjusted according to actual needs, and the fire fighting operation can be put into operation in time.

[0025] The fire extinguisher box is equipped with a variety of fire extinguishing agent storage tanks, which can accurately select the corresponding agents for different types of fires, changing the situation that the traditional fire extinguisher box with a single agent is difficult to deal with complex fires, greatly improving the pertinence and effect of fire extinguishing. At the same time, the intelligently controlled flow regulating valve and adjustable spray nozzle can adjust the agent flow in real time according to the size of the fire and the situation at the fire scene, ensuring efficient and accurate fire extinguishing operations, effectively curbing the spread of fire and reducing fire losses.

[0026] The fire extinguisher box monitors the tunnel environment in real time through smoke concentration sensors and air quality sensors. When it detects that the smoke concentration exceeds the standard, it starts the axial flow fan and the electric regulating valve. The axial flow fan cooperates with the smoke exhaust duct to quickly inhale and exhaust the smoke. At the same time, the air purification filter can effectively purify the air and improve the ventilation conditions at the fire scene, which is beneficial to the linkage with the ventilation system in the tunnel, greatly improving the smoke exhaust efficiency, reducing the obstacles of smoke to rescue and personnel evacuation, and buying precious time for fire fighting and rescue.

[0027] The fire box achieves multi-channel self-power supply through vibration energy collectors, temperature difference power generation modules and solar panels. In the tunnel, ground vibration caused by vehicle driving or fire, temperature difference inside and outside the box, and solar energy in the light area can all be converted into electrical energy and stored in the lithium battery pack. The charging management chip ensures efficient storage and stable output of electrical energy, getting rid of dependence on external power sources. Even in remote areas where tunnels or fires cause external power supply failures, the smart devices in the box can still operate normally, ensuring that functions such as fire detection and fire extinguishing control are not affected, and continue to provide strong support for tunnel fire safety.

[0044] The smoke exhaust control module includes a mounting base 16 located on one side of the fire protection box 11, and a speed control module is arranged inside the mounting base 16. The output end of the speed control module is connected to an axial flow fan 161, and a connecting pipe 162 is arranged on one side of the axial flow fan 161. A filter plate is arranged between the axial flow fan 161 and the connecting pipe 162. A U-shaped pipe 163 is arranged on one side of the inner wall of the fire protection box 11. One end of the U-shaped pipe 163 passes through the fire protection box 11 and is connected with the connecting pipe 162, and the other end is fixedly connected to a smoke exhaust pipe 164.

[0045] An energy collection and management module is arranged at the outer bottom of the fire fighting box 11, and the energy collection and management module includes a vibration energy collector 17. A central processing unit 18 is arranged at the inner bottom of the fire fighting box 11. The output end of the central processing unit 18 is connected to a temperature difference power generation module 171. One end of the temperature difference power generation module 171 passes through the fire fighting box 11 and extends to the outside of the fire fighting box 11.

[0046] A solar panel 172 is fixedly connected to the top of the fire fighting box 11 , a lithium battery pack 173 is arranged on the inner wall of the solar panel 172 , and a charging management chip is arranged on one side of the lithium battery pack 173 .

[0047] The outer wall of the fire fighting box 11 is provided with a hinge 19 , and the fire fighting box 11 is rotatably connected to a control mainboard 20 via the hinge 19 .

[0048] In this embodiment, when it is necessary to carry the fire extinguisher box into the tunnel, the box frame can be folded along the folding joints to reduce the volume for easy carrying. After that, after carrying the fire extinguisher box to the tunnel site, the front box plate 2, the rear box plate 3, the left box plate 4 and the right box plate 5 are erected along the folding joints in sequence, and the tenon 8 is inserted into the tenon groove 801, and then the top box plate 6 is rotated so that the top box plate 6 rotates with the rotating shaft 7 as the fulcrum, and the clamping block 9 on one side of the left box plate 4 is clamped into the clamping groove 10 on one side of the top box plate 6, so as to be combined into a complete fire extinguisher box 11, and then each module is installed in sequence inside the fire extinguisher box 11;

[0049] Specifically, the assembled fire fighting box 11 is placed in a tunnel. When a vehicle is running or a fire occurs in the tunnel causing the ground to vibrate, the vibration energy collector 17 at the bottom of the fire fighting box 11 senses the ground vibration. At this time, the piezoelectric ceramics inside the vibration energy collector 17 are squeezed and deformed, thereby converting mechanical energy into electrical energy. At the same time, the temperature difference power generation module 171 always monitors the temperature difference between the inside and outside of the fire fighting box 11 and continuously generates electrical energy. If the fire fighting box 11 is in an area with light, the solar panel 172 starts to collect solar energy and generate electricity. When the equipment in the fire fighting box 11 needs electricity, the charging management chip controls the lithium battery pack 173 to stably output electricity according to the power demand of the equipment.

[0050] Furthermore, when the fire fighting box 11 is in a standby state in the tunnel, the multi-sensor fusion module continuously collects environmental data in the tunnel and transmits the data to the central processing unit 18 in real time. The central processing unit 18 analyzes the data in real time to determine whether there is a fire hazard in the tunnel. When the sensor data is abnormal, such as the temperature sensor 12 detects a sharp rise in temperature, the smoke sensor 13 detects that the smoke concentration exceeds the standard, and the gas sensor 14 and the flame sensor 15 detect combustible gas or flame signals, the central processing unit 18 determines whether a fire has occurred and the type of fire (Class A solid fire, Class B liquid fire, Class C gas fire, etc.) based on the internal fire judgment algorithm and through comprehensive analysis of multiple sensor data. Once it is determined that a fire has occurred, the central processing unit 18 transmits a signal to the control main board 20 according to the type of fire, and sends an opening instruction to the corresponding flow control valve 120 by operating the control main board 20. For example, for Class A solid fire, open the flow regulating valve 120 corresponding to the dry powder storage tank 112; for Class B liquid fire, open the flow regulating valve 120 corresponding to the water-forming foam storage tank 114; for Class C gas fire, open the flow regulating valve 120 corresponding to the CO2 storage tank 113, and then the fire extinguishing agent reaches the telescopic hose 118 through the corresponding delivery pipe 116 and the connecting vertical pipe 117. The spraying angle and length can be adjusted at will by pulling the telescopic hose 118. Then the fire extinguishing agent reaches the spray nozzle 119 through the telescopic hose 118, and then the spray nozzle 119 accurately sprays the fire extinguishing agent to the fire source according to the preset spray angle and flow rate for fire extinguishing. During the fire extinguishing process, the multi-sensor fusion module continuously monitors the fire scene situation, and the control main board 20 can adjust the spray parameters of the spray nozzle 119 in real time according to the feedback data to ensure the fire extinguishing effect.

[0051] Furthermore, when a fire occurs in the tunnel and a large amount of smoke is generated, the smoke concentration sensor 167 and the air quality sensor 168 are used to monitor the environmental data in the tunnel. When the smoke concentration exceeds the set threshold, the speed control module immediately starts the axial flow fan 161 and adjusts its speed after receiving the sensor signal, and opens the electric regulating valve 166 at the same time. At this time, the axial flow fan 161 inhales the smoke in the fire scene through the connecting pipe 162. When the smoke passes through the filter plate, the filter plate intercepts the large particles and impurities mixed in the scene. Then the smoke passes through the U-shaped pipe 163 to the smoke exhaust pipe 164, and then the smoke is filtered through the air purification filter 165 to remove harmful particles and gases, so as to discharge the purified air, so as to achieve effective discharge of smoke in the tunnel and improve the ventilation condition at the fire scene. When the fire is controlled, the smoke concentration in the tunnel gradually decreases to a safe range. At the same time, when the air quality returns to normal, the speed control module receives the sensor signal again at this time, and then gradually reduces the speed of the axial flow fan 161 until it stops running.

[0052] Furthermore, when the fire scene in the tunnel is under control, the modules in the fire fighting box 11 stop running. At this time, the electric energy from different modules is integrated and stabilized by the charging management chip, and then the lithium battery pack 173 is charged with appropriate voltage and current according to the charging characteristics of the lithium battery pack 173. At the same time, the battery status of the lithium battery pack 173 is monitored in real time during the charging process to ensure the safety and efficiency of charging. For example, when the fire fighting box 11 is needed again in the future, the charging management chip controls the lithium battery pack 173 to output electric energy stably according to the power demand of the modules in the fire fighting box 11, so as to power the various module devices inside the fire fighting box 11.

[0053] Embodiment 2:

[0054] Reference Figure 2-5 Based on the first embodiment, a method for using a portable intelligent fire fighting box for a tunnel is provided, comprising the following steps:

[0055] Step S1: sequentially assemble the bottom box board 1, the front box board 2, the rear box board 3, the left box board 4, the right box board 5, and the top box board 6 along the folding joints to form a complete fire fighting box 11, and then sequentially assemble each module into the fire fighting box 11;

[0056] Step S2: placing the fire fighting box 11 in the tunnel, and when a vehicle is running or the ground vibrates due to a fire, the energy collection and management module is used to generate electrical energy to reserve energy for subsequent equipment operation;

[0057] Step S3: The temperature sensor 12 tracks the temperature change in the tunnel in real time, the gas sensor 14 monitors the concentration of combustible gas, and the flame sensor 15 captures the flame characteristics. Then the multi-sensor fusion module transmits the collected data to the central processor 18 in real time;

[0058] Step S4: The central processor 18 receives the data transmitted from the multi-sensor fusion module and determines the fire type and fire size according to the fire judgment algorithm. At the same time, the smoke concentration sensor 167 monitors the smoke concentration in the tunnel. If the smoke concentration exceeds a predetermined threshold, the central processor 18 sends a smoke exhaust request to the axial flow fan 161;

[0059] Step S5: Based on the fire judgment result, the central processor 18 determines the required fire extinguishing type, then controls the flow regulating valve 120 of the corresponding storage tank and accurately adjusts the flow of the agent, and selects an adaptive spraying mode according to the actual situation on site to control the fire. During the spraying process, the multi-sensor fusion module continuously monitors the fire condition, and the central processor 18 adjusts the spraying mode in real time based on the feedback data. Each storage tank is equipped with an independent pressure sensor 121 and a liquid level sensor 122 to monitor the pressure and liquid level of the agent in real time;

[0060] Step S6: After receiving the smoke exhaust request, the central processing unit 18 controls the operation of the smoke exhaust control module, and then drives the axial flow fan 161 and the electric control valve 166 to open. The axial flow fan 161 absorbs the smoke in the fire scene through the connecting pipe 162, and the filter plate intercepts the large particles mixed in the fire scene. Then the smoke enters the smoke exhaust pipe 164 through the U-shaped pipe 163, and the purified air is discharged after being filtered by the air purification filter 165. During this process, the smoke concentration sensor 167 and the air quality sensor 168 continuously monitor the smoke concentration and air quality. The central processing unit 18 adjusts the opening of the electric control valve 166 in real time according to the monitoring data until the smoke concentration is reduced to a safe range.

The axial flow fan (161) absorbs the smoke in the fire scene through the connecting pipe (162), and the filter plate intercepts the large particles mixed in the fire scene. Then, the smoke enters the smoke exhaust pipe (164) through the U-shaped pipe (163), and the purified air is discharged after being filtered by the air purification filter (165). During this process, the smoke concentration sensor (167) and the air quality sensor (168) continuously monitor the smoke concentration and air quality. The central processing unit (18) adjusts the opening of the electric regulating valve (166) in real time according to the monitoring data until the smoke concentration is reduced to a safe range.
